9. The method for using the automation equipment for cutting polytetrafluoroethylene tubing according to any one of claims 1-8, comprising the steps of:
01. inserting the cut polytetrafluoroethylene tube into the self-adaptive annular clamp holder (9) and adjusting the cut polytetrafluoroethylene tube to a proper position;
02. the three rotary clamping plate spiral push rods (905) are respectively rotated, the clamping plate spiral push rods (905) are in spiral connection with the guide push holes (902) to enable the clamping plate spiral push rods (905) to move inwards, the positioning clamping plates (903) are pushed towards the central shaft direction of the self-adaptive annular clamp holder (9) to be in close contact with the pipe fitting, and the pipe fitting is respectively clamped and fixed through the three directions;
03. the nozzle connecting frame (803) is controlled to move through the nozzle adjusting mechanical arm (10), the particle injector (8) is started, particles are conveyed to the injector nozzle (802) through the particle injector (8), and the particles are uniformly sprayed on the cutting surface of the cut pipe fitting through the injector nozzle (802);
04. starting two groups of cutter driving pieces (304), driving an elliptical cutter (303) to rotate by the cutter driving pieces (304), then controlling a cutting spiral pushing cylinder (5) to push a cutter frame connecting push rod (4) upwards, pushing a pressing spring (306) upwards by the cutter frame connecting push rod (4), driving two cutters together with a double cutter frame (3) to move upwards on a longitudinal support plate (2), enabling the elliptical cutter (303) to contact a pipe fitting, cutting the pipe fitting, and enabling the pressure between the two cutters and the pipe body to be constant by the elasticity of the pressing spring (306) during cutting;
05. after cutting is finished, a reset driving motor (6) is started, the reset driving motor (6) rotates to drive a reset bevel gear (7) to rotate, the reset bevel gear (7) is connected with a reset rack (307), and then the double-knife-rest (3) is driven to move down rapidly to perform knife withdrawal reset, so that a blade can be returned to an initial position rapidly and accurately after cutting is finished, and the whole cutting process of polytetrafluoroethylene tubing is finished.
